System for spraying the interior of a container

A method for spraying the inside of a container having an opening to the interior of the container that is offset from the center or rotational axis of the container, the method comprising the steps of:

• a) supporting a non-linear boom having a front end and back end elevated above the front end on a support structure that moves vertically to elevate the guide system at different positions and that further includes a guide system having a first gear for dynamically engaging and supporting the non-linear boom at a first position along the length of the non-linear boom and a second gear positioned at a second position along the length of the non-linear boom from the first gear and at a height differing from the first gear to moveably support the non-linear boom, where the first gear is in communication with a reversable motor that when actuated turns the first gear to move the non-linear boom from a retracted to extended position, the non-liner boom being curved along its length from the front to back end of the non-linear boom and includes a conduit member having a front end and back end, where the conduit member includes at least one spray nozzle positioned on the front end of the conduit;
• b) aligning the opening to the interior of the container with the front end of the non-linear boom by moving the support structure vertically to raise or lower the guide system;
• c) inserting the non-linear boom into the opening in the container by moving the non-linear boom from a retracted to an extended position through actuation of the motor;
• and
• d) spraying medium into the interior of the container through the at least one spray nozzle at a pressure and for a time sufficient to spray the interior of the container, where the medium is received through the conduit member by a supply line running to the back end of the non-linear boom and guided to the back end of the non-linear boom by at least one channel positioned on the guide system to prevent the supply line from interfering with the movement of the guide system.

A method for spraying the inside of a container having an access opening to the interior of the container that is offset from the center or rotational axis of the container, the method comprising the steps of:

• a) inserting a curved boom having a front end and back into the access opening to the container, where the curved boom has an angle of curvature along its length and includes a first and second conduit member each having a front end and back end, where the back end is elevated above the front end, where the first conduit member includes at least one spray nozzle positioned on the front end of the conduit and where the second conduit member includes an airline running through the second conduit member to supply compressed air to the spray nozzle, where the curved boom is supported in an elevated position by a support structure;
• and
• b) introducing a medium into the first conduit member through a flexible water line by elevating the flexible supply line to the elevated back end of the first conduit member and connecting the flexible water line to the elevated back end of the first conduct member;
• c) introducing compressed air into the airline by elevating an airline to the back end of the second conduit member and running the airline through the second conduit member to supply compressed air to the spray nozzle,
• d) providing channels on the support structure for guiding the flexible water line and airline to the back end of the non-linear boom so that the flexible water line and airline do not interfere with the support structure;
• and
• d) discharging the medium through the spray nozzles at a pressure by entraining the medium with the compressed air and for a time sufficient to spray the interior of the container.
